I was at cedar point yesterday, and was wearing my Fluttershy shirt. I saw four bronies, and two possible bronies or maybe just people who knew about the show. In fact, I saw two in a row. The first one I met I was walking down towards this restaurant and he was like, "I love your shirt!". Later, made eye contact with a girl who had a Rainbow Dash shirt and we both laughed. And then while leaving I came across a girl who yelled, "I love your shirt!" and a guy wearing the same shirt I was.

EDIT: As for the two I mentioned earlier, there were two red-haired brothers standing in line, at least I think they were brothers, and they saw my shirt and cracked up saying, "Fluttershy? Oh wow."
